Ulwandle olungajulile kakhulu eplanethi uLwandle i-Azov futhi luyinto eyingqayizivele yemvelo. Umhlaba ocebile wezimbali nezilwane uvezwa endaweni yamanzi, futhi emanzini kukhona udaka ophulukisayo, osetshenziselwa ukwelapha.
Kodwa-ke, okwamanje isimo semvelo soLwandle i-Azov senziwa ngamandla umsebenzi womuntu, okuholela ekuwohlokeni kwemvelo. Okokuqala, abantu babheka indawo yamanzi njengomthombo wokucebisa. Babamba izinhlanzi, bathuthukise izikhungo zezempilo kanye nemisebenzi yezokuvakasha. Ngokulandelayo, ulwandle alunaso isikhathi sokuzihlanza, amanzi alahlekelwa izakhiwo zawo eziwusizo. Umsebenzi wokulondolozwa kwemvelo kwabantu kule ndawo awuhambelanga endaweni yesibili kuphela, kepha uye eshumini.
Izici zokungcola koLwandle lwase-Azov
Okwamanje, kunezinkinga eziningi zemvelo zolwandle:
- ukungcola kwamanzi okwenziwa yizimboni, ezolimo nezamanzi angcolile angcolile;
- Ukuchitheka kwemikhiqizo kawoyela ebusweni bamanzi;
- ukudoba okungagunyaziwe ngobuningi nangezikhathi zokuzala;
- ukwakhiwa kwamadamu;
- ukukhishwa kwemithi yokubulala izinambuzane olwandle;
- ukungcoliswa kwamakhemikhali ngamanzi;
- ukulahlwa kukadoti olwandle ngabantu abaya eholidini ogwini;
- ukwakhiwa kwezakhiwo ezahlukahlukene ngasogwini lwendawo yamanzi, njll.
Ukungcoliswa kwemfucumfucu yezimboni
Le nkinga isebenza kakhulu emanzini amaningi eplanethi. Amanzi emifula agelezela kuyo adala umonakalo omkhulu oLwandle lwase-Azov. Sezivele zigcwele izinsimbi ezisindayo, izinto ezinobuthi ezingacutshungulwa emanzini, kepha ezinobuthi empilweni yasolwandle. Inani lama-thiocyanate lidlula inkambiso evunyelwe izikhathi eziyi-12, kanye nokuba khona kwama-phenols kasikhombisa. Le nkinga ivela emisebenzini yamabhizinisi asezimbonini, angazihluphi ngokuhlanza amanzi, kodwa ngokushesha ayilahle emifuleni ethwala ukungcola olwandle.
Ungasindisa kanjani uLwandle lwe-Azov?
Kunezibonelo eziningi zokufa kwezindawo zamanzi. Ngakho-ke uLwandle iCaspian lusengcupheni yenhlekelele, futhi i-Aral Sea inganyamalala ngokuphelele ngesikhathi esifushane. Izinkinga zemvelo zoLwandle lwase-Azov zibalulekile, futhi uma ungakwenzi ukuvikelwa kwemvelo okusebenzayo, inkinga yale ndawo yamanzi nayo ingasondela enhlekeleleni. Ukugwema le miphumela, kufanele uthathe isinyathelo:
- lawula ukuphathwa kwamanzi angcolile ezimboni nawomasipala;
- lawula ezokuthutha zasolwandle;
- ukunciphisa ukuthunyelwa okuyingozi olwandle;
- ukuzalela izinhlobo zasolwandle zezilwane nezinhlanzi;
- izinhlawulo ezinzima zabazingeli abangekho emthethweni;
- qapha njalo isikhala samanzi nolwandle lolwandle.
